Answer:
Imagery/Descriptionary words:
two mallards drifting
one dunks for a snail
a mourning dove lifts off
a red-eyed virea catches
mergansers paddle
at dusk a wild goose
one blue egg
Explanation:
The way I remember this is I say the poem in my head and find a word that is 'louder' than the others. Ex. one blue egg. One and Blue are both imagery words because you can imagine one egg and a blue egg. Hope this helps!
